Ultrasonic flowmeters can only measure liquids, such as tap water, sewage, seawater, pure water, and water, and relatively clean liquids. If the liquid contains a large amount of agglomerated dirt or a large number of air bubbles, ultrasonic transmission and reception will be affected. Should not use the external clamp type ultrasonic ultrasonic flowmeter. Most oils and gases are also not suitable for use.
    The main steps for the installation of an external clamp type ultrasonic flowmeter are: selection of mounting points, input of parameters, determination of sensor installation distance, application of a couplant, and bonding of a sensor. Most users can clearly understand how the above steps are performed when they read the manual. However, according to the method, the traffic cannot be displayed. The main reasons are:
1. To understand the installation distance automatically calculated by the flowmeter is too mechanical, to accurately set the distance to the mm to install, in fact, this distance is only a reference distance, due to the influence of the pipeline environment, such as the wall thickness deviation, the inner wall is not smooth, it is possible Causes the deviation of the acoustic signal. Therefore, we have a very practical method for actual installation: first fix the upstream sensor, then press the M90 ​​button on the host to check the signal strength and quality. In general, both UP and DN should be above 80, and Q below 50. The flow meter cannot measure normally.
2. In the user installation problem, the user often has UP and DN are 0 when checking the M90 ​​menu. The main reason for this is that the couplant is not applied or the clamp is not tightened. Another reason is that there is no pipe in the installation. water.
3. The reason why the Q value is 0 is mostly due to improper distance. At this time, open the M90 ​​menu and move the downstream sensor slowly. When the Q value gets a maximum value, it can be fixed.
Our factory majors in producing Single Port,Double Port and Small Port for infusion bag and bottle in clinical pharmaceutical packaging. The port is used to connect the combined top cap with the infusion bag or bottle .The joint is produced in a clean plant which reaches to 100000-100 million class grade cleanliness .We will have a professional testing for the materials we use before starting production, only when it is proved to be qualified, we will go to the next phase. During the productive process, we will choose some samples from the cargo from time to time to check the quality. For more details , pls feel free to contact us.
